Watch a video on privacy and security.
Many Google Docs users add personal information to their documents, spreadsheets and presentations, and this information is safely stored on Google's secure servers. Data stored in Docs is not accessed by search engines (and won't appear in search results) unless you or someone you've shared a document with has published the document and posted the URL on a public site. That means by default, your data is private, unless you grant access to others and/or publish your information.
Additionally, to keep your data private, it's important to have a strong password, to not share that password with others, and to understand the sharing options in Google Docs. To learn more, please read the section on Privacy and Security in our Help Center.
